Protein is a critical nutrient in cattle, pig, poultry, sheep, horse and pet foods.
Although protein supplements are high in cost, they are sometimes necessary in order to meet the animal’s nutritional requirements. An adequate protein content in feed products is important for animal health and productivity, as well as for farm profitability. The protein requirements of cattle vary with age, size, and expected performance.
During lactation, larger cattle typically require more pounds of crude protein per day than smaller animals, but as a lower percentage of their total dry matter intake. In other words, lighter cattle require higher quality feeds and forages at lower quantities compared with heavier cattle. Cattle requirements for crude protein rise with increasing lactation and rate of gain. Protein is required for milk production and reproductive tract reconditioning after calving.
